On the development of sensible heat storage for concentrated solar power applications: Thermo-fluid management and materials
Sensible heat storages have extensive use in thermal energy deployment, including concentrated solar power (CSP) applications. Usually, CSP pants demand various techno-economic features in sensible heat storage, such as ... -
Turbulent Free Moist Convection over Horizontal Surfaces
The heat and moisture loss from water surfaces are important in many natural and industrial systems. For example, the natural water cycle where water evaporates from the lakes, rivers, and seas, rises in the atmosphere, ... -
Interaction of bubble(s) and buoyant rigid particles with vortical structures: Towards understanding bubbly turbulent flows
Bubbly turbulent flows occur in many places, such as in chemical reactors and geophysical applications, besides interest from the drag reduction perspective using injected bubbles in a (water) boundary layer. In these ... -
Design and development of lateral force-controlled tribosystems
In a tribo-system, the frictional resistance during a sliding process depends on several parameters. These parameters include the interacting materials, their surface topography, contact conditions such as normal load, ... -
Vaned Diffuser Effect on Centrifugal Compressor Performance and Stall
A centrifugal compressor is a mechanical device that helps to achieve higher pressure ratios at lower mass flow rates. It is used in many applications such as turbochargers, cruise missiles, and turbojet engines where ... -
Classical Approach to Understanding the Impact Dynamics of Hollow Droplets
Compound droplets are utilized in applications ranging from the preparation of emulsion to biological cell printing and additive manufacturing. Here, we report on the impact dynamics of a compound hollow droplet on a ... -
Multi-linear Disassembly Path Determination: A Geometric Approach
This thesis presents a geometric approach for determining the orientation-preserving disassembly paths of polyhedral assembly components. Exact disassembly path determination of the components is essential because the ... -
Discrete particulate description of elastic structures undergoing geometrically nonlinear deformation and dynamic particle interaction
The mechanical behaviour of deformable bodies in a particulate environment has been an area of increasing interest across a wide spectrum of systems and scale. A composite ensemble of deformable structures and discrete ... -
Mechanobiology of cell-substrate interactions
Cell adhesion to substrates is a complex process facilitated by focal adhesion (FA) complexes that help them perform vital cellular functions like migration, growth, and division. Cells probe their surroundings through ... -
Studies on modeling the mechanics of slender elastic ribbons
Ribbons are slender structures characterized by three disparate geometric dimensions: length >> width >> thickness. Such a dimensional disparity enables ribbons to bend, buckle, twist and crease response to simple loading ... -
Mechanics of collective cell migration on substrates of different stiffness
Collective cell migration is characteristic in many physiological processes such as wound closure, morphogenesis, and cancer tumour metastasis. Experiments on cell monolayers demonstrated the formation of finger-like ... -
Steady Sedimentation of Particles in Long Vertical Tube and Effect of End Boundary Conditions on Convective Motion
Sedimentation – settling of particles in a fluid- is observed in nature like rain droplets and dust particles in the atmosphere, and in a variety of industrial processes, like to clarify liquid as well as separate particles ... -
Experimental and Numerical Studies on Chemically Active Flame Inhibitors
Fire hazards pose an increasingly potent threat to modern societies. Early identification and mitigation of fire hazards are crucial to avoid the loss of human lives and property. Recent research suggests that finely-atomized ... -
Design and Development of Force Sensor for measurement of Tactile Friction
The sense of touch, along with the other senses, decides the perception of world around us. We touch, grip, and wear various products in our day-to-day life, be it the constant interaction we have with our mobile phones, ... -
Vapor Mediated Interaction in Droplets
Controlling internal flow in evaporating sessile droplets is desirable across applications ranging from lab-on-chip medical diagnostics, DNA profiling to surface patterning. Diffusion-limited evaporation in droplets exhibits ... -
Analysis of Transcritical CO2 and CO2+ Propane Mixtures for Tropical Cooling Applications
The increasing global average ambient temperatures coupled with stringent environmental regulations has turned the focus on natural working fluids such as Carbon dioxide (CO2), and hydrocarbons for use in the refrigeration ... -
Turbulent Free Convection Over Horizontal Surfaces
This thesis deals with turbulent free convection in a horizontal fluid layer above a heated surface. The work can be roughly divided into two parts. In the &st part a model is proposed for the near wall dynamics in ... -
Measuring Three-dimensional Deformations of Elastic Ribbons
Experimental techniques to measure and visualize kinematics in structural and solid mechanics range from humble strain gage rosettes to sophisticated digital image correlation methods. This thesis develops a stereo ... -
